MEANS FOR BURNING AND RUNNING IN THE CRANK-SHAFT BEARINGS O'F AN AUTOMOBILE.

Application filed April 11, 1922. Serial No. 551,656.

To all whom it may concern.

Be it known that we, CHARLES S. BUSH and MICHAEL J. Kenn, citizens of the United States, residing at the city and county of Kalamazoo, State .of Michigan, have invented certain new and useful Improvements in Means for Burning and Running in the Crank-Shaft Bearings of an Automobile, of which the following is a specification.

This invention relates to improved means for burning and running in the crank shaft bearings of an automobile.

The object of the invention is to provide a simple and effective means for supporting the motor body and doing the same in such manner as to prevent the splashing of oil and to effectively align and maintain the alignment of a motor.

Objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices andmeans described in the following specification. he invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a side elevation of an improved structure with the motor in position for burning in.

Fig. II is a detail sectional elevation on line 22 of Fig. I, showing the arrangement and disposition of the clamping chain means.

Fig. III is a detail perspective end view of the motor shifted to the running in position.

Fig. IV is an enlarged detail sectional view on line 4i-4t of Figs. II and III.

In the drawings similar reference numerals refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Oonsidering'the numbered parts of the drawing by their numbers, 1 is the main casing provided with legs 2 and a combined motor base and legs 3 at the opposite end. 4 is an electric motor connected by a shaft 5 containing a universal joint 6 driving an encased train of gears 7, not necessary to detail.

The connection 8 is provided at the proper level to receive the flange 9 of the crank shaft 10 of a motor. The engine cylinder block 11, shown diagrammatically, is disposed on a suitable support 12 within a sink top 13 of the general frame 1 of the machine. An engine supporting base 120 is formed within the said sink top 13, being in the form of a ledge. The support 12 is adjusted and alined by suitable set screws 14 (see Fi II). This adjustment is principally to properly raise the engine and shift the same into alinement with the connection 8. The set screws are thumb screws so that they may be readily manipulated by the fingers of the operator to accomplish this result.

The motor is clamped in place by the roller bearing chain 15 secured to an eye 16 at one side and disposed over a clamping bracket 17 at the top constructed with a seat 18 to permit the free operation of the roller chain 15, which is provided with a screw bolt 19 and nut 20 engaging bracket 21 at the opposite end (see Fig. II).

The particular structure is adapted to fit the standard Ford motor engines, the adjusting means being disposed within the sink top 13, making it unnecessary to provide any packing to prevent the escape of oil as the sink collects and returns the oil without any such provision. The adjustment necessary is only slight, usually represented by the slight variation due to the wear of parts. 7

The gear train 7 is connected by its flange 8 to the flange 9 and strong power is applied to break the engine shaft loose from the babbit bearing which has been poured about it. hen the shaft has been freed from the babbit of the bearing the engine is then turned the other side up andthe flange 9 of the crank shaft is secured to the lower flange 22 which runs the shaft rapidly in that position, the lower part being enclosed temporarily by the crank case 23, which insures oiling of the parts by the splashing system. Because the engine is disposed in the sink the oil is retained without any effort to make oil-tight joints and is used effectively until the engine has runlong enough to be efiectively run in.

The sink construction or support 1 could, of course, be used with other styles of clamping means, although not so conveniently and effectively, and the clamp means might be used effectively in other relations, but each lends itself especially to combined action with the other.

In place of the electric motor 4 a gasoline engine motor of an automobile or tractor can be substituted on the motor base 3. The same may also be driven from a line shaft by pulley, by clutch, or in any other way.

I've therefore desire to claim the combination specifically as well as the various features broadly, as pointed out in the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. The combination of a suitable main framework with a motor supporting base thereon, a supporting frame with adjusting thumb screws disposed on said base, a

raised surrounding wall around the same, gear trains with suitable connections at one end thereof with means for driving the same, a clamp for the engine motor comprising a clamping block with curved seat, and a roller sprocket clamp chain disposed across said seat and connected to one side of the motor base and adjustably connected by bolt and nut to the opposite side, coaeting as specified.

2. The combination of a suitable main framework with a motor supporting base surrounding wall around the same, gear trains with suitable connections at one end thereof with means for driving the same, and a clamp for the engine motor, coacting as specified.

4. The combination of a suitable main frameworr with a motor supporting base thereon, a supporting frame with adjusting thumb screws disposed on said base, gear trains with suitable connections at one end thereof with means for driving the same,

a clamp for the engine motor comprising a clamping block with curved seat and a roller sprocket clamp chain disposed across said seat and connected to one side of the motor base and adjustably connected by bolt and nut to the opposite side, coacting as specified.

The combination of a suitable main framework with a motor supporting base thereon, a raised surrounding wall around the same, gear trains with suitable connections at one end thereof with means for driving the same, and a clamp for the engine motor, coacting as specified.

6. The combination of a suitable main framework with a motor supporting base thereon, gear trains with suitable connections at one end thereof with means for driving the same, a clamp for the engine motor comprising a clamping block with' curved seat and a roller sprocket clamp chain disposed across said seat and connected to one side of the motor base and ad justably connected by bolt and nut to the opposite side, coacting as specified.

7. In a structure of the class described, the combination of a suitable main frame work with a motor supportingbase thereon, an adjustable frame disposed on the said base adapted to carry the said motor, a raised surrounding wall disposed about the said frame and base of said motor. and means for driving the said motor.

In witness whereof, we have hereunto set our hands and seals in the presence of two witnesses.
